1.4. The Truck Package
Harben® truck packages have been designed to the highest standards. It is important that
you take time to read the information provided here so that you understand how to make the
most of the truck package and use it in accordance with the instructions. Harben® truck
packages are powerful pieces of industrial equipment and should only be operated by
competent users who understand that serious injury or death can occur through misuse.
The truck package described in this operation and maintenance manual are intended to be
used for high-pressure water jetting pumping applications.
They will remove soft blockages, tree roots and hard scale, liquefying fats and restoring drain
flow by blasting high-pressure water through a drain nozzle connected to the end of a high-
pressure hose. Some models can be fitted with jump jets kits to increase the effective cleaning
distance.
Harben truck packages use diesel engines to power a high-pressure water pump up to 4,000
psi and 18 GPM.
Additional accessories can be purchased from Harben®, such as: floor cleaners, jetting guns
and jet pumps which extend the range of work that can be carried out with the jetter. Safety
information relating to individual accessories is provided later in this section.
